Disable specific days in material ui calendar in React

I am using material-ui v0.20.0 for React js This is my DatePicker component

<Field
    name='appointmentDate'
    label="Select Date"
    component={this.renderDatePicker}
/>

renderDatePicker = ({ input, label, meta: { touched, error }, ...custom,props }) => {
    return (
        <DatePicker 
          {...input} 
          {...custom} 
          autoOk={true} 
          floatingLabelText={label}
          dateForm='MM/DD/YYYY' 
          shouldDisableDate={this.disabledDate}
          minDate={ new Date()}
          value={ input.value !== '' ? input.value : null }
          onChange={(event, value) => input.onChange(value)} 
        />
    );
};

What should I write in disabledDate(){...} if I want to disable any of the day/s ?

Here is the sample code that needed to be added. You can refer this link for more details - https://material-ui.com/components/pickers/#date-time-pickers

You can add condition according to your need in order to disable date.

import React from 'react';
import DatePicker from 'material-ui/DatePicker';

function disableWeekends(date) {
  return date.getDay() === 0 || date.getDay() === 6;
}

function disableRandomDates() {
  return Math.random() > 0.7;
}
/**
 * `DatePicker` can disable specific dates based on the return value of a callback.
 */
const DatePickerExampleDisableDates = () => (
  <div>
    <DatePicker hintText="Weekends Disabled" shouldDisableDate={disableWeekends} />
    <DatePicker hintText="Random Dates Disabled" shouldDisableDate={disableRandomDates} />
  </div>
);

export default DatePickerExampleDisableDates;
